    摘要: An amine is prepared by cleaving a carbamate of the formula I wherein R1=hydrogen, alkyl, aryl or phenyl group, R2=alkyl, aryl or phenyl group, wherein R1 and R2 are independently substituted or unsubstituted, wherein the cleaving of the carbamate is performed in the presence of an acid of the formula II wherein R3, R4 and R5 are independently alkyl or phenyl group, wherein R1, R2, R3, R4 and R5 are the same or different.

    摘要: A process for preparing diols or triols made up of a1) reacting at least one monoolefin having 4 to 20 carbon atoms with hydrogen peroxide and formic acid in the presence of water to form a mixture or a2) reacting at least one monoolefin alcohol having 4 to 20 carbon atoms first with formic acid, and then reacting the product formed thereby with hydrogen peroxide in the presence of water to form a mixture, b) removing, by distillation, the water and formic acid from the mixture obtained in a1) or a2), c) reacting the mixture obtained from b) with an aliphatic alcohol in the presence of a sulfonic acid to form the diol or triol and at least one formic ester by-product, and d) optionally removing, by distillation, the at least one formic ester by-product formed together with any residual at least one aliphatic C1-C4-alcohol to isolate the diol or triol.
